Set of artificial flagstones

Abstract

A set of artificial stones is disclosed for use in creating a covering for a supporting surface. Each artificial stone preferably includes a base portion for placement on the supporting surface, which base portion is shaped as a right regular prism for patterned, fitting arrangement of the flagstone with like flagstones in the set to produce a continuous surface covering. The base portion has a regular base contour. The stone further includes a top portion with a facing surface, the facing surface having an irregularly shaped top contour different from the base contour and an intermediate portion connecting the top portion with the base portion. The intermediate portion has an inclined wall extending between the top portion and a sidewall of the base portion. The irregular top contours of the stones, simulate the appearance of natural stone.

1 . A set of artificial stones for covering a supporting surface, comprising at least two artificial stones, each having a base portion for placement on the surface, the base portion having a polygonal base contour and being shaped as a right regular prism for fitting arrangement of the flagstones in the set to produce a continuous covering for the surface, and a top portion connected with the base portion, the top portion having a facing with an irregular top contour fitting within the base contour; the top contour on one flagstone in the set being different from the top contour of every other flagstone in the set. 
     
     
         2 . A set of artificial stones including at least two artificial stones for covering a supporting surface, each artificial stone comprising
 a base portion for placement on the supporting surface, a top portion and an intermediate portion connecting the top and base portions,   the base portion being shaped for patterned, fitting arrangement of the stone with like stones to produce a covering of stones on the supporting surface in a regular pattern, the base portion having a flat polygonal base with a regular base contour and upstanding right angle base walls, each with parallel side edges, a straight bottom edge at the base contour and an irregular top edge adjacent the intermediate portion;   the top portion having a facing surface and depending top walls, the facing surface having an irregularly shaped top contour, and the depending top walls having irregularly shaped top and bottom edges of differing shape; and   the intermediate portion having an inclined wall extending between the top portion and the base portion and the inclined wall including multiple planar wall sections having straight side edges, each planar wall section connected to the bottom edge of at least one of the top walls and the top edge of at least one of the base walls, for generating visible joints of irregular width and outline between adjacent like stones in an installed condition; and   the top contour of one stone in the set being different from the top contour of every other stone in the set.   
     
     
         3 . The set of artificial stones of  claim 2 , wherein the height of the sidewall of the base portion varies along the base contour in each stone in the set. 
     
     
         4 . The set of artificial stones of  claim 3 , wherein each wall section is inclined at an acute angle of at most 25° relative to the connected base wall. 
     
     
         5 . The set of artificial stones of  claim 4 , wherein the angle is about 15°. 
     
     
         6 . The set of artificial stones of  claim 1 , wherein the base portion has a flat bottom for placement on the supporting surface and the depending top walls being oriented perpendicular to the flat bottom. 
     
     
         7 . The set of artificial stones of  claim 1 , wherein each artificial stone is a dry molded flagstone and the base portion has multiple corners, at least one of the corners being chamfered, beveled or rounded. 
     
     
         8 . The set of artificial stones of  claim 7 , wherein at least one pair of opposing corners in each stone is chamfered, beveled, or rounded. 
     
     
         9 . The set of artificial stones of  claim 1 , wherein the facing surface in at least one of the stones has at least two areas of different elevation. 
     
     
         10 . The set of artificial stones of  claim 1 , wherein the facing surface in at least one of the stones has at least two irregularly shaped areas of respectively different elevation. 
     
     
         11 . The set of artificial stones of  claim 10 , wherein the facing surface of the top portion of at least one of the stones has at least one irregularly shaped protrusion or depression for giving the top portion the appearance of natural stone. 
     
     
         12 . The set of artificial stones of  claim 11 , wherein the facing surface has at least one irregularly shaped protrusion and at least one irregularly shaped depression. 
     
     
         13 . The set of artificial stones of  claim 1 , wherein all of the artificial stones are shaped and constructed as a paving stone. 
     
     
         14 . The set of artificial stones of  claim 13 , wherein the paving stone is a dry cast paver. 
     
     
         15 . The set of artificial stones of  claim 1 , wherein, in each artificial stone, the base contour is polygonal and the top contour is polygonal and has the same number of sides as the base contour, the base portion has a side wall for each side of the polygonal base contour and the top contour is rotated or shifted relative to the base contour so that a plane of at least one depending side wall of the top portion intersects with a plane of one base wall of the base portion.
